- Variables/fields/parameters store a single value.
- They range from 1 byte to 8 bytes in most languages.
- At the statement
m = new PVector();the operatornewcreates a contiguous memory block enough to fit in all PVector’s non-staticfields. - And when it’s done, it returns the 1st memory address of that block.
- And finally, that 1st memory address is stored in the field m as a reference value.
- Now, when you do
pressLoc = m, you’re assigning field pressLoc w/ the exact value of m. - After that assignment, both m & pressLoc fields point to the same PVector object, b/c they now store the same 1st memory address value of it.
- In other words, they’re now alias to the same object.
